Chubu chachitsulo chosasunthika ndi chitsulo chozungulira, chozungulira, cha makona anayi chokhala ndi gawo lobowo ndipo palibe zitsulo zozungulira.Machubu achitsulo osasunthika amapangidwa ndi ingots kapena ma billet olimba omwe amabowoleredwa m'machubu a capillary ndiyeno kutentha kukulungidwa, kuzizira kapena kuzizira.

Chitoliro chopanda chitsulo chokhala ndi gawo la dzenje, mipope yambiri yomwe imagwiritsidwa ntchito popereka madzi, Mu kupinda ndi mphamvu ya torsion pa nthawi yomweyo, Poyerekeza chitoliro chachitsulo ndi zitsulo zozungulira ndi zina zolimba. chigawo chachitsulo, chomwe chimagwiritsidwa ntchito kwambiri popanga zigawo zamakina ndi zida zamakina, monga pobowola zitsulo zamafuta.

Kupanga machubu osasunthika kuli ndi mbiri ya zaka pafupifupi 100. Abale a ku Germany a Manismann adayamba kupanga nkhonya yopukutira mipukutu iwiri mu 1885, kenako adapanga makina ogubuduza chitoliro mu 1891, ndipo Swiss RCStiefel adapanga makina opangira chitoliro chodziwikiratu. Mu 1903, makina ochulukitsira osiyanasiyana, monga makina opitilira chitoliro ndi makina akukankhira chitoliro, adayamba kupanga mafakitale amakono opanda zitsulo zachitsulo. anatengedwa.

Extrusion atolankhani ndi nthawi ozizira anagubuduza mphero kusintha zosiyanasiyana ndi khalidwe la zitsulo machubu.Mu 1960s, chifukwa cha kusintha mosalekeza anagubuduza chitoliro mphero, zikamera wa atatu masikono nkhonya, makamaka kupambana kwa ntchito ya mavuto kuchepetsa makina ndi mosalekeza. kuponyera billet, kwathandizira kupanga bwino komanso kupititsa patsogolo mpikisano wa chitoliro chopanda msoko ndi chitoliro chowotcherera.

M'zaka za m'ma 1970, chitoliro chopanda msoko ndi chitoliro chowotcherera chikuyenda bwino ndi mzake, ndipo dziko lonse lapansi limatulutsa chitoliro chachitsulo chikuwonjezeka ndi 5% pachaka. poyamba anapanga dongosolo kupanga anagubuduza zosiyanasiyana lalikulu, sing'anga ndi ang'onoang'ono mapaipi.Nthawi zambiri, chitoliro mkuwa komanso utenga ndondomeko billet mtanda anagubuduza ndi perforation, chitoliro mphero anagubuduza ndi koyilo kujambula.

Kugwiritsa ntchitondi gulu la machubu achitsulo opanda msoko

Ntchito: Seamless zitsulo chubu ndi mtundu wa chuma gawo zitsulo, ali ndi udindo wofunika kwambiri mu chuma cha dziko, chimagwiritsidwa ntchito mafuta, makampani mankhwala, kukatentha, siteshoni mphamvu, sitima, kupanga makina, galimoto, ndege, ndege, mphamvu, nthaka. , zomangamanga ndi zankhondo.

Gulu:

(1) Malingana ndi mawonekedwe a gawo lomwe lagawidwa kukhala: chubu chozungulira, chopangidwa ndi mawonekedwe apadera

(2) malinga ndi zinthu: mpweya zitsulo chitoliro, aloyi zitsulo chitoliro, zosapanga dzimbiri chitoliro, gulu chitoliro

(3) Malinga ndi kugwirizana akafuna: ya threaded kugwirizana chitoliro, kuwotcherera chitoliro

(4) Malinga ndi kupanga akafuna: otentha anagudubuzika (extrusion, pamwamba, kukulitsa) chitoliro, ozizira kugudubuza (kukoka) chitoliro

(5) Malinga ndi ntchito: chitoliro chowotchera, chitoliro cha mafuta, chitoliro cha payipi, chitoliro chomanga, chitoliro cha feteleza.

Seamless zitsulo chubu kupanga ndondomeko

Njira yayikulu yopanga machubu otentha opindika opanda chitsulo (njira yoyendera kwambiri):

Kukonzekera ndi kuyang'anira chitoliro cha chitoliro → kutentha kwa chitoliro → perforating → kugudubuza chitoliro → kutenthetsanso chitoliro chopanda kanthu → kukonza (kuchepetsa) m'mimba mwake → kutentha kwa kutentha → kuwongola chitoliro chomalizidwa → kumaliza → kuyang'anira (zosawononga, thupi ndi mankhwala, kuyang'anira siteshoni) → nkhokwe

(2) Cold anagubuduza (chojambula) chosasokonezeka zitsulo chitoliro kupanga ndondomeko

Kukonzekera billet → pickling ndi mafuta → kugudubuza ozizira (kujambula) → kutentha kutentha → kuwongola → kumaliza → kuyang'anira

The kupanga ndondomeko otaya tchati otentha-anagulung'undisa seamless zitsulo chubu ndi motere:
